Nginx 配置默认虚拟主机

　　　　　　1.1 默认虚拟主机

修改主配置文件nginx.conf ，在结束符号 } 上面件一行配置改写如下

# vim /usr/local/nginx/conf/nginx.conf

意思是 /usr/local/nginx/conf/vhost下面的所有以.conf 结尾的文件都会加载，这样我们就可以把所有虚拟主机配置文件放到vhost目录下面了。

# mkidr /usr/local/nginx/conf/vhost

# cd /usr/local/nginx/conf/vhost

# vim default.conf

server

{

listen 80 default_server; //有这个default_server标记的就是默认虚拟主机

server_name aaa.com;

index index.html index.htm index.php;

root /data/nginx/default;

}

# /usr/local/nginx/sbin/nginx -t

# /usr/local/nginx/sbin/nginx -s reload

# echo "default_server" > /data/nginx/default/index.html

#curl -x127.0.0.1:80 aaa.com

default_server

#curl -x127.0.0.1:80 1212.com

default_server

1.2 用户认证

# cd /usr/local/nginx/conf/vhost/

# vim test.com.conf

用户认证
server
{
listen 80;
server_name test.com;
index index.html index.htm index.php;
root /data/nginx/test.com;

location /
{
auth_basic "Auth";
auth_basic_user_file /usr/local/nginx/conf/htpasswd;

}

}

# yum -y install httpd //安装httpd 也可以安装之前编译安装的apache2.4

# htpasswd -c /usr/local/nginx/conf/htpasswd aming //创建aming用户

# /usr/local/nginx/sbin/nginx -t

/usr/local/nginx/sbin/nginx -s reload

核心语句就两行，auth_basic打开认证 auth_basic_user_file指定用户密码文件

#mkdir /data/nginx/test.com

# echo "test.com" > /data/nginx/test.com/index.html

# curl -I -x127.0.0.1:80 test.com

进入网页输访问 test.com 会出现如下图所示对话框

如果针对某个目录做用户认证，需要修改location后面的路径

1.3 域名重定向

server
{
listen 80;
server_name test.com test1.com test2.com;
index index.html index.htm index.php;
root /data/nginx/test.com;

if ($host != 'test.com'){
rewrite ^/(.*)$ http://test.com/$1 permanent;

}
}

# /usr/local/nginx/sbin/nginx -t

#/usr/local/nginx/sbin/nginx -s reload

curl -x127.0.0.1:80 -I test1.com/123.txt

1.4 访问日志

先来查看Nginx的日志格式

# grep -A2 log_format /usr/local/nginx/conf/nginx.conf

到虚拟主机配置文件中指定访问日志的路径：

server

{
listen 80;
server_name test.com test1.com test2.com;
index index.html index.htm index.php;
root /data/nginx/test.com;

if ($host != 'test.com')
{
rewrite ^/(.*)$ http://test.com/$1 permanent;
}

access_log /tmp/1.log combined_realip;

}

# /usr/local/nginx/sbin/nginx -t

# /usr/local/nginx/sbin/nginx -s reload

# curl -x127.0.0.1:80 test.com/111

# cat /tmp/1.log

# vim /usr/local/sbin/nginx_log_rotate.sh 写入一下内容

#! /bin/bash
## 假设nginx的日志存放路径为/data/logs/d=`data -d "-1 day" +%Y%m%d`
logdir="/data/logs"
nginx_pid="/usr/local/nginx/logs/nginx.pid"
cd $logdir
for log in `ls *.log`
do
mv $log $log-$d
done
/bin/kill -HUP `cat $nginx_pid`
